Acta, 85 33, In the above procedure, steps 1 and 2 can be done once and for all, yielding results that are valid for all states and nuclear charges, and the steps need not be repeated. In Chapter 1, we showed that such a set of generalized Sturmian basis functions obey a potentialweighted orthonormality relation in direct space IE r?

Convergence of the separable-expansion method for low-energy positronhydrogen problems, Phys. Carrying out the integrations in B. The numbers above the levels represent degeneracies.

P H If we compare In relativistic theory, space and time combine to form a pseudo-Euclidean space-time continuum Minkowski space. H molecule ion, Hf, Proc. Introduction To Atomic Spectra. Atomic Astrophysics and Spectroscopy.


Substituting the root with the smallest numerical value into equation 3. In this book, we shall call a set of antisymmetrized isoenergetic solutions, with this choice of Atomid, a set of Goscinskian configurations, to honor his pioneering work. The calculated energies include corrections for the motion of the nucleus.


These are the simplest of the eigenvectors. As Z increases, the non-relativistic calculation show the electron to be much less tightly bound than the spectroscopic experiments.

The set of simultaneous equations 9. The Yukawa potential, J. Making use of this knowledge, and also making use of 9. Data Tables, 21, 49, Thus we can see gemeralized difference between the Goscinskian configurations and configurations based on Coulomb Sturmians: In Chapters 3, 4, 5 and 6, such configurations are applied to calculations of the spectra and properties of few-electron atoms and ions.

Thus the generalized Sturmian method offers an extremely rapid and convenient method for the calculation of large numbers of excited states of few-electron atoms and atomic ions. If we include all of the primitive configurations with these principle quantum numbers, the block will give us gdneralized x matrix to diagonalize in equation 3.

A, 4 1 The Sturm-Liouville equation, which is named after them, can be written in the form: Government Printing Office, Washington 25 D. Applying the generalized Laplacian operator A to the homogeneous polynomial shown in equation Applications to the He problem, J.


A, 33 Andrea Caligiana and Dr. Calculations using the generalized Sturmian method are presented and compared with experimental results from the NIST database. Spectra of atoms stuurmians molecules. Generalized Sturmians And Atomic Spectra.


sturmiians A basis set consisting of symmetry-adapted configurations was used for both calculations shown in the first column and those shown in the second. Using the Fourier convolution theorem, 2.

For example, calculated core-ionization energies for the 3-electron isoelectronic series are shown Table 5. Duchon, C ; Dumont-Lepage, M.

The 4dimensional hyperspherical harmonics of the standard set can be obtained from the formula ,u2,u3 8. Indeed, the situation resembles that encountered in perturbation theory.

The curves in the figure, starting from the bottom, correspond to 2s3s 3 S states, equation 3. A, 25 2 Atomic Generaluzed and Atomic Structure.
